Application filed January 14, 1916. Serial No. 72,045.

To all whom itmay concern: I i

Be it known that I, WILLIAM R. HARRIS,

a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have inventedcertain newand useful Improvements in Speed-Regulating Devices, of which thefollowing. is 'a specification. I v

This invention relates to a regulating'or governing device for regulating or controlling the speed of internal combustion en- 'gines.

The object of the invention is to provide simple and efiective means for regulating the speed of an engine equipped with a governor, so arranged, that the governor Will be effective to maintain a uniform speed at any rate. desired.

A further object of the invention isto pro vide for regulating or changing, from a dis; tant point, the speed of a governor con trolled engine.

In the accompanying drawings:-Figure 1 is a side elevation of my improved controlling and regulating mechanism. Fig. 2 is a detail of the regulating wheel. is an end view of the devices shown in Fig. 1. Fig. 1 is a section on the line 41 of Fig. 3. Fig. is a section on the line 55 of Fig. 1.

The mechanism herein described is especially adapted for regulating the speed of internal combustion engines, used for pumping oil, cleaning, bailing and pulling wells. It frequently becomes necessary to employ the engine for the different operations as described above. In these operations it is de sirable that the engine be run at different rates of speed than when pumping oil. It is also desirable to provide means for regulating the speed of the engine from a point removed from the engine, such as the derrick floor, so that a minimum or safe maximum speed may be maintained without the constant attention of the operator when performing the different operations of pumping, bailing and pulling Wells, and at the same time leave the governor, with which such engines are equipped in effective condition to maintain a uniform speed at any rate of speed desired.

Referring to the drawings, 1 represents a governor of any conventional form, the governor shown in the present case being one of the well known centrifugal ball type, the

Fig. 3

balls being rotated from any suitable point of power, such as the shaft 2, through the medium of the beveled gears 3 and 4 and the shaft 5, the shafts 2 and 5 being supported in the bracket 6. The balls operate in the sliding sleeve 7 which is provided w th a groove 8 to receive the trunnions 9 of a yoke 9 formed on the outer end of a crank arm 10, secured to the shaft 11, the other end of the shaft having a crank arm 12 which is pivotallyconnected to the throttle rod 13, which in turn is connected to gas throttle valve of the engine to regulate the supply of gas necessary to maintain uniform speed at any rate of speed desired. In the the hub 14 of a grooved wheel or pulley '15.

The hub of the pulley, which is extended as indicated at 1 1 isin turn journaled in the stationary bearing 16 formed on the extension 17 of the bracket 6.

J ournaled on a pin 18 which extends from a suitable support 19 located in convenient reach of the operator on the derrick floor or other controlling point, is a grooved wheel or pulley 20, a cordor cable 21 passing about the pulleys and serving to impart rotary movement to the pulley 15 when the pulley20 is rotated. 'A'spring 22 interposed between the hub of the pulley 20 and a washer 23, to which tension is applied by the nut 24 threaded on the end of the pin 18, serves to frictionally hold the pulley 20 in any desired position.

The result of this construction is that the operator by turning the wheel 20, rotates the wheel 15 in the bearing 16 and at the same time, due to the eccentric mounting of the shaft 11 in the hub lLof the Wheel 15, raises or lowers the throttling rod 13 so as to regu late the speed of the engine. During this operation the outer end of the crank arm 10 is held immovable in a vertical direction by reason of the walls of the slot 8 on the sleeve 7, but the end of the arm can move transversely across the vertical axis of the sleeve to compensate for the changed position of the shaft 11, the result of the operation being to raise and lower the crank arm 12 and hence the throttle rod 13 so as to increase or diminish the supply of gas to the engine. At the same time the governor 1 is left in operative relation with the parts so as to maintain uniform speed of the en- V gine, at any rate of speed desired, whether high or low, as determined by the position of the regulating Wheel 20. Also the Wheel 15, is limited by a circular shaped lug 25 arranged about the hub of the wheel 15 and adapted to contact with a stop '26 on-the' bearing 16. The latter construction is essential to the successful operation of the governor.

I I Copies of this patent may be obtained for Having thus described my invention, I claim l a 1. In a throttle controlling mechanism, a throttle operating device, an automatic governor, a shaft having an operative connection with said governor and also with the throttle operating device, an eccentric bearing for said shaft, and a manually operated throttle regulating device having a connection with said eccentric bearing'for changing the position of the same so as to cause said shaft to thereby change the position of said throttle operating device. v

2. In a throttle controlling mechanism, a throttle operating device, an automatic governor, a movable bearing, a shaft eccentrically mounted in said bearing,a crank arnr on said shafthaving an operative connection with said governor, a second crank arm on said shaft, having a connection with the throttle operating device, and manually operated means for moving said bearing to thereby change the position of said shaft to regulate the position of the throttle operating device. a 1

3. In a throttle controlling mechanism, a

throttle operating device, an automatic governor, a stationary bearing, a movable bear ing concentrically mounted in said station ary bearing, a shaft eccentrically mounted 1n ysaid movable bearing, a crank arm on said shaft having an operative connection with said governor, a second crank arm having an operatlve connection with the throttle operating device, and means for revolving said I movable bearing in said stationary bearing to change the position of said shaft and hence said throttle operating device.

4.. In a throttle controlling mechanism, an automatic governor, a throttle operating device, a stationary bearing, a movable bearing concentrically mounted in said station ary bearing, a shaft eccentrioally mounted in said movable bearing, a pair of crank arms on said shaft connected respectively with said governor and said operating de-' vice, a grooved wheel connected with said movable bearing, a second grooved wheel arranged to be manually operated, a cord or cable connecting said Wheels, and means for 'yieldably holding said manually operated wheel in its operative position.

5. In a throttle controlling mechanism, a throttle operating device, an automatic governor, a rotatable part, a connection between said governor and said throttle operating device eccentrically and loosely mountedxin said rotatable part, and manually operated devices connected with said rotatable part for changing the positionof the same.

6. In a throttle controlling mechanism, a throttle operating device, an automatic governor, a rotatable part, a connection between said governor and said throttle operating device eccentrically and loosely mounted in said rotatable part, and manually operated devices connected with said rotatable part for changing the position of the same, said manually operated devices comprising two grooved wheels, one connected to said r0- tatable part and the other located at a distance therefrom together With a cord or cable connecting the same.

In testimony whereof, I have hereunto set my hand this 8th day of January, 1916.
